PNEUMATIC STACKEK SPECIFICATION forming part of Letters Patent No. 652,452, dated June 26, 1900. Appnoonoo fnooi Novomtoo 19,1898. sono No. 696,875. oromodoi.)

To all whom t may concern:

y Beit known that I,JoHN L. BARTHOLOMEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois7 have invented certain new and useful- Improvements in Pneumatic Stackers; and I do declare the following to be a full, clear, and exactdescription ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyl ing drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure l is a side elevation of a pneumatic stacking mechanism embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective of the stacker and the rear end of the thresher. Figs. et, 5, 6, and 7 show details.

In the drawings, A designates the rear end of a threshing-machine, which may be of several styles.

A' designates a verticaltube or duct by which straw and chad from the interior of the thresher are conducted upwardly to the discharge trunk or duct. The latter consists, in the embodiment of my invention herein illustrated,vof an inner curved section B, a second section B', telescopically connected to the section B, and an outer section B2, telescopically mounted upon the second section B' and provided at its outer end with a delecting hood or shield for guiding the straw escaping from the outlet at the end of said section B2. As the present improvements relate more particularly to mechanism for automatically adjusting this hood or straw-delector with relation to the body of the trunk, I do not believe it necessary to either illustrate or describe in detail the construction or manner of mounting and supporting the trunk. It is sufcient to say that C indicates aperipherally-toothed ring or base upon which the stacker-tube is mounted, and c designates a pinion for rotating said ring and tube about a vertical axis. Suitable mechanism (not shown) is provided for automatically reversing the direction of revolution of the pinion c at predetermined intervals, so that the stacker-tube will be vibrated through the arc of the circle concentric with the axis of the ring C, and at T, I have indicated one form of mechanism for elongating the discharge-trunk to correspond to the increase in the height of the stack.

With machines heretofore devised for utilizing a blast of air for stacking straw means have been provided for depositing the straw at various points in a line extending transversely of the stack, (being the line of movement of the outer end of the discharge trunk or tube;) but the result has been that the straw was deposited in a relatively-narrow rid ge-like form, and it was necessary to manually distribute the straw to points beyond such ridge to provide a proper stack. i The object of the present invention is to provide means by which the straw will be automatically discharged uniformly over the' entire top of the stack.

As shown in the drawings, the hood or deiiector at the outer end of the stacker-trunk consists of three telescoping sections D D D2. The inner of these sections D is rigidly secured to the tube-section B2, while the other two sections D D2 are pivotally connected together and to said inner section -at CZ.. Short sections of chain or cable d are provided for limiting the outward or downward movement of the sections D D2 relatively to each other and to the section D. When the lower or' outer section D2 of the deflector is in the position indicated in full lines-in Fig. 1, for example-it will be seen that such section acts to limit the outward motion of the straw and to cause the same to be deposited at points between the inner end of the 4cut-away portion b2 of the outer tube-section and said deflector-section, and it will also be seen that if the said outer deiiecting-section D2 should be rocked about its pivot d at any instant the straw would be carried to points relatively farther from the body of the stacker-tube. To eect this automatic vertical movement of the deliector, I provide the following devices: O designates a cylindrical or tubular rock-shaft mounted in bearings o o on the second duct-section B', and O designates a rock-shaft which is mounted in bearings o o on the outer section B2, the inner end of this shaft O fitting within the shaft O, so as tov move longitudinally thereof, but connected thereto to vibrate about its longitudinal axis IOO therewith. At its outer end the shaft O is provided with a crank-arm o2, to the free end of which is connected a short chain-section o3, the lower end of which may be engaged with either of a series of apertures d6, formed in a bar d?, secured to ythe deflector-section D2. To the rock-shaft O, near the inner end thereof, is connected a crank-arm O2, the free end of which is connected to one end of a link P, the other end of which is connected'to the sprocket N. The sprocket N is mounted on a shaft N4, journaled in the supportingframe of the stacker-duct, and is connected by a sprocket-chain N' with another sprocketwheel N2. The latteris mounted upon a horizontal shaft n, which carries a bevel-pinion n', that meshes with a bevel-gear n2, secured to a vertical shaft n3. This shaft n2 is provided at its lower end with a pinion n4, which meshes with the piece of a segmental rack N3, rigidly and stationarily secured in position upon the framework on the thresher A and situated concentrically with the ring or base C, by which the stacker-trunk is horizontally vi brated. It will be seen that as the sprocket N is rotated in the manner hereinbefore described the link P and crank O3 will cause the compound rock-shaf t O O to vibrate about its longitudinal axis, and the upward movement ofthe crank O2 at the outer end of said shaftwill act to raise the deiiector-section D2. As the revolution of the sprocket N brings the parts P O3 O into their original positions the weight of the section D will cause it to move downwardly about its pivot at d.

Any suitable power devices may be provided for driving the pinion c, such as a train of gearing of any well-known or preferred character connecting said pinion with a ba-nd wheel or shaft mounted on the thresher.

At V is indicated the casing of the fan or ejector, by which the straw-moving blast of air is created, said casing communicating with the uptake duct A';

From theabove description and the drawings it will be seen that as the stacker tube or trunk is rotated about thevertical axis of the cylindrical base C the deliector at the outer' end of such duct will be automatically Vibrated about its pivot, and the straw escaping from the section B2 will be guided to points relatively nearer or farther from the outer end of the duct on aline transverse to that of the horizontal movement of such end,- so that the straw will be uniformly distributed over the entire top of the stack.

\ The means for elongating and shortening the deiiector-duct indicated by T, as above 2 stated,- consist of a rope or cord p, a chain t',- a sprocket-wheel t2 with a crank t3, the cord t being fastened at t4 to the sliding section B2 and passing around the wheels t5 and t6, the said wheels being supported on the duct-carrying bar T', which is held by the adjusting and extensible brace T2.
